Plants require energy to perform photosynthesis, in which glucose is formed from carbon dioxide and water, and stores energy. This is a(n) reaction.

Anabolic reaction

Explanation:

Living cells undergo metabolic reactions from time to time. Metabolic reactions constitutes the series of building up and breaking down of molecules. The building up of larger organic molecules from smaller ones is referred to as ANABOLISM. A very vivid example of an anabolic process is the photosynthesis that occurs in the Chloroplast of plant cells.

In photosynthesis, plants combine inorganic carbondioxide (CO2) and water (H2O) to form a more complex organic molecule called glucose. Anabolic processes like photosynthesis usually require energy to build up the molecules, in the case of the photosynthesis, plants uniquely get this energy by trapping light energy from sun to power this process.

the truman doctrine was an american foreign policy whose stated purpose was to counter soviet geopolitical expansion during the cold war. it was announced to congress by president harry s. truman on march 12, 1947, and further developed on july 12, 1948, when he pledged to contain threats to greece and turkey.
